Mercury Remote Control Adapter Harness | 892473A01

Overview

This remote control adapter harness is used when updating or converting older Mercury ignition and control wiring to a newer setup. It’s a simple bridge piece that lets different connector styles communicate without cutting or modifying the boat’s wiring. Most techs use it during repowers or control upgrades where the engine and helm hardware are from different generations. It keeps the job clean and avoids guesswork at the dash.

Key Features

• Control Connector Conversion – Allows older engine wiring to interface with newer control or key switch harnesses.

• Factory Mercury Wiring Layout – Maintains proper pin alignment and signal routing.

• Mechanical Control Support – Designed for mechanical throttle and shift systems.

• Plug-In Harness Design – Eliminates splicing and reduces installation errors.

Engine & Boat Compatibility

• Mercury outboards

• Mechanical control system

• Conventional ignition systems

• Mid range FourStroke engines

Performance & Practical Benefits

Once installed, electrical signals pass through cleanly with no delay or intermittent behavior. Starting and control functions feel steady and predictable, just like a matched system should. The harness keeps wiring tidy behind the dash, which helps prevent long-term electrical issues. It’s a practical fix that makes mixed-generation setups behave normally.

Why Buy OEM

OEM adapter harnesses keep pin layouts and signal resistance exactly where Mercury expects them. That means reliable communication, fewer troubleshooting headaches, and better long-term durability. It’s the safest way to adapt systems without creating future problems.
